Last year, after Al Gore said in a speech that climate change was responsible for various extreme weather events around the globe, he got spanked by Oxford climate scientist Myles Allen, who wrote a column in the Guardian entitled, “Al Gore is doing a disservice by overplaying the link between climate change and the weather.”

I have to wonder if Allen is now thinking the same thing of NASA climatologist James Hansen. Because, as New York Times reporter John Broder puts it, Hansen, this week, has “roiled” the climate science community “with a new scientific paper explicitly linking high concentrations of carbon dioxide and other heat-trapping gases to recent severe heat waves and drought.”

The controversial paper was published on Monday in the Proceedings of the National Academies of Sciences (PNAS). A day earlier, Hansen previewed the study’s findings in a Washington Postop-ed, in which he made this jaw-dropping assertion:

It is no longer enough to say that global warming will increase the likelihood of extreme weather and to repeat the caveat that no individual weather event can be directly linked to climate change. To the contrary, our analysis shows that, for the extreme hot weather of the recent past, there is virtually no explanation other than climate change.
